Modified Formthotics influence lower limb muscle activity in flat arched feet.
In this study, participants underwent rigorous protocol for classifying foot posture and were screened for their suitability (flat-footedness) for the study. They were then given both rearfoot medial wedge modified Formthotics and casted prescription orthoses with a 20 degree cast correction. EMG lower limb muscle amplitude data was gathered with the results showing a change in both tibialis posterior and peroneus longus amplitude with the modified Formthotics. Further research is needed to determine whether these changes affect clinical outcomes.
